Bio-based phytic acid represents a promising approach to endow textile with effective flame retardancy due to its eco-friendliness and high P content, but it suffers from poor washing durability on textile. In the present work, the reactive phytate urea salt (PUS) was synthesized using phytic acid and urea, and it was applied as durable intumescent flame retardant (FR) agent to improve the flame retardancy of silk fabric via pad-dry-cure technique. The chemical structure of PUS and its potential cross-linking action with silk fiber were studied, the thermal resistance, smoke/heat emission ability, flame retardancy and functional mechanism of modified silk were investigated. The PUS modification imparted good FR ability to silk fabric and significantly inhibited the smoke and heat emission of silk. The modified silk sample possessed the low char length of about 6 cm and the high LOI value of 34.2%. The modified silk fabric had the self-extinguishing ability after 35 home washings, which should be assigned to the covalent bonding of PUS on silk. Besides, the FR modification also showed little influence on the handle and mechanical performance of silk fabric. The char residue analyses suggested an intumescent FR mechanism for the modified silk. The synthesized PUS shows great possibility to act as durable and formaldehyde-free FR agent for enhancing the fire safety of silk fabric.

Nano-magnesium hydroxide (nano-Mg(OH)2) serves as a promising flame retardant (FR) filler for plastics, but it remains a challenge to endow textiles with effective and durable FR ability. In the present work, Mg(OH)2 nanoparticles with an average diameter of 68 nm were prepared via the double precipitation method with Tween 80 as surface modifier. Then, nano-Mg(OH)2 was used to prepare the functional silk fabric with enhanced FR ability and smoke suppression to reduce the fire risk of silk through surface coating technique using polycarboxylic acid as cross-linker. The morphology and structure of nano-Mg(OH)2 were studied, and the smoke/heat emission ability, FR ability and durability, and functional mechanism of the coated silk were also investigated. The nano-Mg(OH)2 coating imparted high FR property to silk and greatly decreased the smoke/heat generation ability of silk. The coated silk fabric also displayed self-extinguishing action after 15 washing cycles, demonstrating good washing durability for the coated silk fabric. The coated silk obtained dense and continuous char residue, exhibiting excellent charring ability. This study proves that nano-Mg(OH)2 could serve as an effective and sustainable FR agent for enhancing the fire safety of silk fabric.

The present study facilely prepared the hydrophobic and flame-retardant (FR) multifunctional coating on silk textile through ferric ion chelation route, and focused on multifunctional abilities and mechanisms of ferric salt on silk. Morphology and structure properties of the modified silk were characterised by scanning electron microscope, atomic force microscopy and X-ray diffraction analyses. The functional abilities, mechanisms and durability were also studied. The multifunctional silk with self-extinguishing ability (char length: 10.1 cm) and hydrophobic effect (water contact angle (WCA): 126.1°) could be obtained using only 0.25 g L−1 ferric salt. The modified silk still had desirable functionalities after five robust launderings. The hydrophobic ability is mainly dependent on the increased surface roughness. Thermal stability and char residue analyses indicated the condensed phase FR mechanism of functional silk. The present study provides a cleaner and cost-effective process to develop hydrophobic and FR multifunctional coating on silk surface by ferric metal salt modification.

The immobilization of biocatalysts or other bioactive components often means their transformation from a soluble to an insoluble state by attaching them to a solid support material. Various types of fibrous textiles from both natural and synthetic sources have been studied as suitable support material for biocatalysts immobilization. Strength, inexpensiveness, high surface area, high porosity, pore size, availability in various forms, and simple preparation/functionalization techniques have made textiles a primary choice for various applications. This led to the concept of a new domain called-biocatalyst immobilization on textiles. By addressing the growing advancement in biocatalysts immobilization on textile, this study provides the first detailed overview on this topic based on the terms of preparation, progress, and application in wastewater treatment. The fundamental reason behind the necessity of biocatalysts immobilized textile as well as the potential preparation methods has been identified and discussed. The overall progress and performances of biocatalysts immobilized textile have been scrutinized and summarized based on the form of textile, catalytic activity, and various influencing factors. This review also highlighted the potential challenges and future considerations that can enhance the pervasive use of such immobilized biocatalysts in various sustainable and green chemistry applications.

This study facilely developed the durable flame retardant (FR) silk fabric by bonding phosphonate groups to silk fiber through Pudovik addition of diethyl phosphite onto Schiff base aldehyde-amine intermediate, namely Kabachnik-Fields reaction. The cross-linking mechanism between FR agent and silk fiber, the thermal resistance, FR ability and durability, and FR mechanism of the modified silk were studied. The modified silk had increased thermal resistance. The modified silk fabric with diethyl phosphite over 13.8 g/L had the self-extinguishing ability and obtained the char length of lower than 11.0 cm and LOI value of higher than 27.4 %, suggesting high FR ability of the modified silk. The modified silk also reached self-extinction after 15 robust launderings, which should be attributed to the covalent cross-linking of phosphonate groups onto silk fiber. The char residue analyses suggested a condensed charring FR mechanism for the modified silk. The Pudovik addition of diethyl phosphite onto silk macromolecular participated Schiff base intermediate shows great possibility to act as effective and durable FR strategy for silk textile.

Research approaches on the use of ecotechnologies like ozone assisted processes for the decolorization of textiles are being explored as against the conventional alkaline reductive process for the color stripping of the cotton textiles. The evaluation of these ecotechnologies must be performed to assess the environmental impacts. Partial “gate to gate” Life Cycle Assessment (LCA) was implemented to study the ozone based decolorization process of the reactive dyed cotton textiles. Experiments were performed to determine input and output data flows for decolorization treatment of reactive dyed cotton textile using the ozonation process. The functional unit was defined as “treatment of 40 g of reactive dyed cotton fabric to achieve more than 94% color stripping”. Generic and specific data bases were also used to determine flows, and International Life Cycle Data system (ILCD) method was selected to convert all flows into environmental impacts. The impact category “Water resource depletion” is the highest for all the ozonation processes as it has the greatest relative value after normalization amongst all the impact indicators. Electricity and Oxygen formation were found to be the major contributors to the environmental impacts. New experimental conditions have been studied to optimize the impacts.

In this study, the borate functionalized caramel (BF-Car) product was prepared by using glucose and synthesized ethanolamine borate ester through Caramel and Schiff base reaction. Then, BF-Car product was applied as effective intumescent flame retardant (FR) system to minimize the fire hazard of protein wool fabric via the facile exhaustion technique. The adsorption performance, smoke and heat suppression capacity, thermal stability, FR efficiency and mechanism of the treated wool fabrics were investigated. The BF-Car treatment endowed brown color and good FR ability to wool fabric, and significantly inhibited the smoke and heat emission of wool. The treated wool fabrics with a weight gain of 9.2% had the self-extinguishing ability, and still reached self-extinction after 5 home washings. The thermal stability analysis and char residue analyses suggested a condensed FR mechanism for the treated wool fabric. The BF-Car treatment finely affected the softness and tensile strength of the fabric. The present prepared BF-Car material shows great possibility to act as sustainable chemicals for enhancing the fire safety of wool fabric.

Flavin mononucleotide (FMN) derived from Vitamin B2, a bio-based fluorescent water-soluble molecule with visible yellow-green fluorescence, has been used in the scope of producing photoluminescent and glow-in-the-dark patterned polyester (PET) nonwoven panels. Since the FMN molecule cannot diffuse inside the PET fiber, screen printing, coating, and padding methods were used in an attempt to immobilize FMN molecules at the PET fiber surface of a nonwoven, using various biopolymers such as gelatin and sodium alginate as well as a water-based commercial polyacrylate. In parallel, air atmospheric plasma activation of PET nonwoven was carried for improved spreading and adhesion of FMN bearing biopolymer/polymer mixture. Effectively, the plasma treatment yielded a more hydrophilic PET nonwoven, reduction in wettability, and surface roughness of the plasma treated fiber with reduced water contact angle and increased capillary uptake were observed. The standard techniques of morphological properties were explored by a scanning electron microscope (SEM) and atomic force microscopy (AFM). Films combining each biopolymer and FMN were formed on PS (polystyrene) Petri-dishes. However, only the gelatin and polyacrylate allowed the yellow-green fluorescence of FMN molecule to be maintained on the film and PET fabric (seen under ultraviolet (UV) light). No yellow-green fluorescence of FMN was observed with sodium alginate. Thus, when the plasma-activated PET was coated with the gelatin mixture or polyacrylate bearing FMN, the intense photoluminescent yellow-green glowing polyester nonwoven panel was obtained in the presence of UV light (370 nm). Screen printing of FMN using a gelatin mixture was possible. The biopolymer exhibited appropriate viscosity and rheological behavior, thus creating a glow-in-the-dark pattern on the polyester nonwoven, with the possibility of one expression in daylight and another in darkness (in presence of UV light). A bio-based natural product such as FMN is potentially an interesting photoluminescent molecule with which textile surface pattern designers may create light-emitting textiles and interesting aesthetic expressions.

Biobased lignin represents one of the possible materials for next-generation flame retardant additives due to its sustainability, environmental benefits and comparable efficiency to other flame retardant (FR) additives. In this context, this study presents the development of FR polyamide 11 (PA11) multifilament yarns and fabric structures containing different industrial lignins (i.e., lignosulfonate lignin (LL), and Kraft lignin (KL)) and zinc phosphinate (ZnP). The combination of ZnP and lignin (KL or LL) at different weight ratios were used to prepare flame retarded PA11 blends by melt mixing using a twin-screw extruder. These blends were transformed into continuous multifilament yarns by the melt-spinning process even at a high concentration of additives as 20 wt%. The mechanical test results showed that the combination of KL and ZnP achieved higher strength and filaments showed regularity in structure as compared to the LL and ZnP filaments. Thermogravimetric (TG) analysis showed the incorporation of lignin induces the initial decomposition (T5%) at a lower temperature; at the same time, maximum decomposition (Tmax) shifts to a higher temperature region and a higher amount of char residue is reported at the end of the test. Further, the TGA-FTIR study revealed that the ternary blends (i.e., the combination of LL or KL, ZnP, and PA11) released mainly the phosphinate compound, hydrocarbon species, and a small amount of phosphinic acid during the initial decomposition stage (T5%), while hydrocarbons, carbonyls, and phenolic compounds along with CO2 are released during main decomposition stage (Tmax). The analysis of decomposition products suggests the stronger bonds formation in the condensed phase and the obtainment of a stable char layer. Cone calorimetry exploited to study the fire behavior on sheet samples (polymer bulk) showed an improvement in flame retardant properties with increasing lignin content in blends and most enhanced results were found when 10 wt% of LL and ZnP were combined such as a reduction in heat release rate (HRR) up to 64% and total heat release (THR) up to 22%. Besides, tests carried out on knitted fabric structure showed less influence on HRR and THR but the noticeable effect on postponing the time to ignition (TTI) and reduction in the maximum average rate of heat emission (MARHE) value during combustion.

3D printing utilized as a direct deposition of conductive polymeric materials onto textiles reveals to be an attractive technique in the development of functional textiles. However, the conductive fillers—filled thermoplastic polymers commonly used in the development of functional textiles through 3D printing technology and most specifically through Fused Deposition Modeling (FDM) process—are not appropriate for textile applications as they are excessively brittle and fragile at room temperature. Indeed, a large amount of fillers is incorporated into the polymers to attain the percolation threshold increasing their viscosity and stiffness. For this reason, this study focuses on enhancing the flexibility, stress and strain at rupture and electrical conductivity of 3D-printed conductive polymer onto textiles by developing various immiscible polymer blends. A phase is composed of a conductive polymer composite (CPC) made of a carbon nanotubes (CNT) and highly structured carbon black (KB)- filled low-density polyethylene (LDPE) and another one of propylene-based elastomer (PBE) blends. Two requirements are essential to create flexible and highly conductive monofilaments for 3D-printed polymers onto textile materials applications. First, the co-continuity of both the thermoplastic and the elastomer phases and the location of the conductive fillers in the thermoplastic phase or at the interface of the two immiscible polymers are necessary to preserve the flexibility of the elastomer while decreasing the global amount of charges in the blends. In the present work based on theoretical models, when using a two-step melt process, the KB and CNT particles are found to be both preferentially located at the LDPE/PBE interface. Moreover, in the case of the two-step extrusion, SEM characterization showed that the KB particles were located in the LDPE while the CNT were mainly at the LDPE/PBE interface and TEM analysis demonstrated that KB and CNT nanoparticles were in LDPE and at the interface. For one-step extrusion, it was found that both KB and CNT are in the PBE and LDPE phases. These selective locations play a key role in extending the co-continuity of the LDPE and PBE phases over a much larger composition range. Therefore, the melt flow index and the electrical conductivity of monofilament, the deformation under compression, the strain and stress and the electrical conductivity of the 3D-printed conducting polymer composite onto textiles were significantly improved with KB and CNT-filled LDPE/PBE blends compared to KB and CNT-filled LDPE separately. The two-step extrusion processed 60%(LDPE16.7% KB + 4.2% CNT)/40 PBE blends presented the best properties and almost similar to the ones of the textile materials and henceforth, could be a better material for functional textile development through 3D printing onto textiles.

In this study, a reactive boron-containing flame retardant (FR) namely glycerol borate citric acid ester (GBCAE) was synthesized using boric acid, glycerol and citric acid, and was applied to improve the flame retardancy of silk fabric. The chemical structure of GBCAE and its potential cross-linking reactions with silk fiber were characterized. The thermal stability, smoke and heat suppression capacity and FR ability of the treated silk were evaluated. The treated silk fabrics with a weight gain of higher than 7.3% had self-extinguishing ability. The FR treatment endowed high thermal stability and excellent flame retardancy to silk, and suppressed the smoke and heat release of silk by nearly 50%. The treated silk could still self-extinguish after 5 washing cycles and showed good washing durability, which is attributed to the covalent cross-linking action between GBCAE and silk fiber. The char residue analyses on morphology and functional groups indicated the intumescent FR mechanism for the treated silk. The prepared GBCAE has great potential to serve as suitable alternative to toxic halogen-based agents for improving the flame retardancy of silk textiles

Wear resistance of conductive Poly Lactic Acid monofilament 3D printed onto textiles, through Fused Deposition Modeling (FDM) process and their electrical conductivity after abrasion are important to consider in the development of smart textiles with preserved mechanical and electrical properties. The study aims at investigating the weight loss after abrasion and end point of such materials, understanding the influence of the textile properties and 3D printing process parameters and studying the impact of the abrasion process on the electrical conductivity property of the 3D printed conductive polymers onto textiles. The effects of the 3D printing process and the printing parameters on the structural properties of textiles, such as the thickness of the conductive Poly Lactic Acid (PLA) 3D printed onto polyethylene terephthalate (PET) textile and the average pore sizes of its surface are also investigated. Findings demonstrate that the textile properties, such as the pattern and the process settings, for instance, the printing bed temperature, impact significantly the abrasion resistance of 3D printed conductive Poly Lactic Acid (PLA) onto PET woven textiles. Due to the higher capacity of the surface structure and stronger fiber-to-fiber cohesion, the 3D printed conductive polymer deposited onto textiles through Fused Deposition Modeling process have a higher abrasion resistance and lower weight loss after abrasion compared to the original fabrics. After printing the mean pore size, localized at the surface of the 3D-printed PLA onto PET textiles, is five to eight times smaller than the one of the pores localized at the surface of the PET fabrics prior to 3D printing. Finally, the abrasion process did considerably impact the electrical conductivity of 3D printed conductive PLA onto PET fabric.

This study aimed at the preparation of caramel product by heating glucose at alkaline condition and its application to develop flame retardant silk fabric. Caramel product was employed to silk through a facile exhaustion approach, and the adsorption property, color depth, flame retardancy and washing durability of caramel on silk fabric were investigated. The adsorption of caramel product on silk at acidic condition imparted brown color and good flame retardancy to silk fabric with self-extinguish ability. The modified silk fabric could still pass the vertical flammability measurement after 15 washing cycles, showing good durability to washing. The bubbling property of caramel during heating is responsible for the enhanced flame retardancy of silk as the formed intumescent char layer could protect silk substrates, revealing a condensed charring mechanism for the modified silk fabric. The caramel product modification exerted little adverse impacts on the handle and tensile strength of silk. The flame retardant modification of silk using eco-friendly and sustainable caramel product is a cleaner production approach compared to the synthetically engineered chemicals.

Polyamide fiber has the requirements for antioxidant and antibacterial properties when applied to produce functional textiles for heath care purposes. In this work, three natural flavonoids (baicalin, quercetin, and rutin) were used to simultaneously impart antioxidant and antibacterial functions to polyamide fiber using an adsorption technology. The relations of the chemical structures of flavonoids with their adsorption capability, adsorption mechanisms, and antioxidant and antibacterial activities were discussed. The Langmuir–Nernst adsorption model fitted the adsorption isotherms of the three flavonoids well. The adsorption kinetics of the three flavonoids conformed to the pseudo second-order kinetic model. Quercetin exhibited the highest affinity and adsorption capability, and imparted the highest antioxidant and antibacterial activities to polyamide fiber; and moreover, its antioxidant and antibacterial functions had good washing durability. This study demonstrates that the treatment using natural flavonoids is an effective way to exhance the health care functions of polyamide fiber.

In the field of pharmaceutical technology, significant attention has been paid on exploiting skin as a drug administration route. Considering the structural and chemical complexity of the skin barrier, many research works focused on developing an innovative way to enhance skin drug permeation. In this context, a new class of materials called bio-functional textiles has been developed. Such materials consist of the combination of advanced pharmaceutical carriers with textile materials. Therefore, they own the possibility of providing a wearable platform for continuous and controlled drug release. Notwithstanding the great potential of these materials, their large-scale application still faces some challenges. The present review provides a state-of-the-art perspective on the bio-functional textile technology analyzing the several issues involved. Firstly, the skin physiology, together with the dermatological delivery strategy, is keenly described in order to provide an overview of the problems tackled by bio-functional textiles technology. Secondly, an overview of the main dermatological nanocarriers is provided; thereafter the application of these nanomaterial to textiles is presented. Finally, the bio-functional textile technology is framed in the context of the different dermatological administration strategies; a comparative analysis that also considers how pharmaceutical regulation is conducted.

In this study, two different types of industrial lignin (i.e., lignosulphonate lignin (LL) and kraft lignin (DL)) were exploited as charring agents with phosphorus-based flame retardants for polyamide 11 (PA11). The effect of lignins on the thermal stability and fire behavior of PA11 combined with phosphinate additives (namely, aluminum phosphinate (AlP) and zinc phosphinate (ZnP)) has been studied by thermogravimetric analysis (TGA), UL 94 vertical flame spread, and cone calorimetry tests. Various blends of flame retarded PA11 were prepared by melt process using a twin-screw extruder. Thermogravimetric analyses showed that the LL containing ternary blends are able to provide higher thermal stability, as well as a developed char residue. The decomposition of the phosphinates led to the formation of phosphate compounds in the condensed phase, which promotes the formation of a stable char. Flammability tests showed that LL/ZnP ternary blends were able to achieve self-extinction and V-1 classification; the other formulations showed a strong melt dripping and higher burning. In addition to this, cone calorimetry results showed that the most enhanced behavior was found when 10 wt % of LL and AlP were combined, which strongly reduced PHRR (-74%) and THR (-22%), due to the interaction between LL and AlP, which not only promotes char formation but also confers the stability to char in the condensed phase.

Chitosan and vitamin B2 sodium phosphate were used as assembly agents to prepare the flame retardant, antibacterial, and colored silk fabric by an electrostatic layer by layer assembly padding technique. The effects of assembly bilayer number on the flammability and thermal degradation of silk fabric as well as the morphological structure of the unburned and burned silk fabrics were studied, and the antibacterial activity of the treated fabric was evaluated. At 5 and 10 assembly bilayers, the treated fabrics had a limiting oxygen index of 28.9% and 32.8%, respectively, and their residual char length in the vertical burning test was shorter than 15 cm, revealing their good flame retardancy. The treated fabric exhibited great antibacterial ability as indicated by the inhibition rate against both S. aureus and E. coli of higher than 90%.

Bio-derived phytic acid exhibits great potential to improve the flame retardancy of textile materials, but it has poor washing durability. In order to address this problem, an efficient, reactive, and phosphorus-containing flame retardant (FR) HPPHBTCA was synthesized using phytic acid, pentaerythritol and 1,2,3,4-butanetetracarboxylic acid, and the chemical structure of HPPHBTCA was characterized. HPPHBTCA was applied to develop FR functional wool fabric, and its FR efficiency and washing durability were evaluated. The wool fabric treated with 0.14 mol/L HPPHBTCA had self-extinguishing performance even after 20 washing cycles during the vertical burning test, presenting good FR ability and resistance to washing. The catalytic char-forming effect of HPPHBTCA contributed to the enhanced FR and smoke suppression properties of wool fabric, and the ester bonds formed between HPPHBTCA and wool fiber resulted in the good washing durability. The HPPHBTCA treatment had a negligible effect on the whiteness, tensile strength and handle of wool fabric. This study offers a novel route to prepare the eco-friendly and durable FR agent using natural and phosphorus-containing compound.

Chitosan (CH)–carboxymethyl cellulose sodium salt (NaCMC) microcapsules containing paraffin oil were synthesized by complex formation, and crosslinked with glutaraldehyde (GTA). The electrostatic deposition of NaCMC onto the CH-coated paraffin oil emulsion droplets was demonstrated by zeta potential and optical microscopy. The optimal process conditions were identified in terms of pH of the aqueous solution (5.5) and CH/NaCMC mass ratio (1:1). Encapsulation of paraffin oil and microcapsule morphology were analyzed by ATR-FTIR and SEM, respectively. The effect of GTA crosslinking on paraffin oil latent heat was investigated by DSC and combined with the values of encapsulation efficiency and core content, supporting the compact shell formation.

In the present work the natural madder dye (Rubia tinctorum L.) was applied to the simultaneous dyeing and functionalization of polyester (PET) fabric. In the first part of the study the color performance and the durability were revealed for exhaustion dyed fabric. The dyed fabric was then characterized with respect to ultraviolet (UV) protection ability and antibacterial activity against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). CIELab color coordinates, namely the positive a* and b* values, confirmed a yellow/orange color of the dyed fabric. From durability tests, the color showed a moderate to good light fastness and good to excellent fastness to washing and rubbing. The madder dye improved both the UV protective performance and the antibacterial activity of the fabric. With 3 % on weight of fiber (owf) the UV protection factor increased up to 106, and the antibacterial activity up to 86 % against both types of bacteria tested.
